@Ambychy buddy, it's not for all the Xperia for the following reasons:
1. In the updater-script you have added as target only /system/app/. Kit Kat 4.4.2 and 4.4.4 have the system/priv-app also that includes some bloat too
example in the Z1 latest Vodafone fw:
b) FBMusicLike.apk etc
2. It's not universal since some devices have other bloat too (some regions or carriers specific fw have this "issues" see examples a and b)
So my advice is to make a new debloat script for the devices that are running 4.4 and the list of the apps that is gonna delete
There are some errors too.
You must write it like this:
and not like this:
also you must add the delete(" before every line.
No problem man
Take a look here also if you want : http://forum.xda-developers.com/show....php?t=2500955
In the 2nd post there is the exact tutorial on how to make the debloat script (for devices that are running 4.3 or lower). If you need any help let me know
